Fully reversible neural networks for large-scale 3D seismic horizon tracking [PDF]
arXiv, 2020 Tracking a horizon in seismic images or 3D volumes is an integral part of seismic interpretation. The last few decades saw progress in using neural networks for this task, starting from shallow networks for 1D traces, to deeper convolutional neural networks for large 2D images. Because geological structures are intrinsically 3D, we hope to see improved

Deep Underground Science and Engineering, EarlyView.A scientometric analysis of 2449 journal articles and a comprehensive review of 336 papers were conducted, discussing and identifying challenges and research gaps in rockburst prediction and prevention and proposing an ontology‐based framework for better decision‐making in underground excavations. Abstract With underground engineering projects becoming

Earthquake Engineering &Structural Dynamics, EarlyView.ABSTRACT Despite the complexity of real earthquake motions, the incident wavefield excitation for soil‐structure interaction (SSI) analysis is conventionally derived from one‐dimensional site response analysis (1D SRA), resulting in idealized, decoupled vertically incident shear and compressional waves for the horizontal and vertical components of the ...

Random and Coherence Noise Attenuation Complete Sequence for 2-D Land Seismic Data Acquired in Iraq [PDF]
arXiv, 2019 Noises are common events in seismic reflection data that have very striking features in seismograms, affecting seismic data processing and interpretation. Noise attenuation is an essential phase in seismic processing data, usually resulting in seismic interpretation improvement that enhances the signal to noise ratio.

Numerical Estimation of Seismic Earth Pressure on Walls of Basements Underlain by Bedrock
Earthquake Engineering &Structural Dynamics, EarlyView.ABSTRACT Dynamic increment of earth pressure is one of the primary parameters in the seismic design of underground basement structures. Both analytical solution and empirical methods developed for rigid walls have been used to estimate the seismic earth pressure.

Seismic Resilience Assessment of a Regional Bridge Network
Earthquake Engineering &Structural Dynamics, EarlyView.ABSTRACT This study evaluates the seismic resilience of a regional bridge network, focusing on the interconnectedness and interdependence among individual bridges and emergency facilities. A framework for resilience assessment is developed and applied to a bridge network in Vancouver, British Columbia, consisting of 11 bridges across seven main routes.

Seismic Fault Preserving Diffusion
, 2007 This paper focuses on the denoising and enhancing of 3-D reflection seismic data. We propose a pre-processing step based on a non linear diffusion filtering leading to a better detection of seismic faults. The non linear diffusion approaches are based on
